There was an increase in the lag phase and slower growth of microorganisms
in the environment containing bacteriophages with the films, compared to control. The
mechanical and physical properties of films, such as thickness, elongation and puncture resistance
showed no significant effects. However, tensile resistance was different between control and treatments.
The addition of bacteriophage altered the film surface, as observed by atomic force microscopy.
